J. ROGERS FOUNTAIN PEN Filed Sept. 28, 1957 R INVENTORY] v Jayfio yergs; BY@)L I Patented Sept. 13, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates'to fountain pens, and particularly to the closing up or capping features of pocket fountain pens.

The principal object of the invention is to provide a simplified, conveniently and economically manufacturable, economically salable, and improved fountain pen and capping device therefor. wherein the cap will not be removable from the pen-barrel, and which capping device will be eflicient, reliable, strong, and durable.

Other objects and advantages will hereinafter appear.

In the accompanying drawing- Fig. 1 is a longitudinal cross-sectional elevation of the fountain pen of this invention.

Fig. 2 is a view similar to Fig. l, but showing the fountain pen as it appears with its cap drawn away when the pen is in operative condi-;''

tion. 20 Figs. 3, 4 show a front and side elevation respectively of the pen-barrel, as it appears before assemblage of the pen during manufacture.

Figs. 5 to 10 show details of the fountain open capping device.

25 Figs. 11, 12 show modifications of the invention.

The cap I of the fountain pen 2, Figs. 1, 6. is completely open at it's terminal 3, and has a cylinder 4 fixed therewithin provided with a pair 30 ofopposite parallel elongated slots 5, Figs. 7, 8, the cap being provided with the usual pocket clip 6, as shown. On the periphery of the ink carrying barrel I are formed guiding lugs 8 for the slots 5, whereby the cap I may be slid over 35 the barrel forwardly to the upward position shown in Fig. l or rearwardly backwardly to the lowered position shown in Fig. 2. The barrel 1 is also provided with a slotted depression 9, Figs. 3, 4, in which is inlaid a T-shaped metallic 40 lug III consisting of a vertical strip II and crosspiece I2. Within cap I, at its terminal 3, is located a collar I3, Figs. 6, 10, which is held in place by a pair of pins fixed to the cap passing slidingly through slightly elongated holes in said 45 collar, as illustrated, the holes I5 permitting a small limited vertical sliding movement of the collar I3, which is thus held and guided by the pins I4. To the collar I3 is held a lid I6 for the terminal of cap I by means of a hinge II, where- 50 by the open terminal of the cap may be thus opened and closed, and to a lug I8 depending from the underside of said lid is in turn hinged at I! a bar 20, Figs. 9, 10, which is thus suspended from the lid I6 and is located between 55 the barrel I and the cap I, as shown in Fig. 2.

The bar 20 is provided with parallel strips 2I forming a slot 22, spri-ngy lateral bends 23 in the said strips, and laterally projecting terminals 24, as illustrated in Fig. 10. In the assemblage of these parts, the strip II lies between 5 the strips 2| for lateral guidance and directioning of the bar 20, the projecting terminals 24 are engageable with the fixed cross-pieces I2 during completion of the upward forward movement of the cap, and the springy bends 23 a lo tensional frictional engagement of the bar 20 with the surface of depression 9 of barrel I as. well as the interior surface of the fixed sleeve 4 of cap I.

During non-use the fountain pen and all its parts appear as 'shown in Fig. 1, with the lid I6 closing up the cap I. When it is desired to use the pen, the cap I is drawn dow 'wa'rdly rearwardly, and thereupon the bar i"'tially actuates the lid IE to open up to the position shown 20 in Fig. 2 about its hinge II. This opening action is automatically performed by the bar 20 pressing upwardly upon hinge I9 and lug I8, since said bar is" initially relatively at rest, due to its frictional and tensional engagement with 25 the barrel I and cap I, the elongated holes I5 simultaneously permitting limited movement of the collar I3 and hinge II required during swinging action of the cover I6. During downward movement of the, cap I to the ultimate position shown in Fig. 2 the bar 20 is carried along therewith and the lid I6 is disposed to the location shown, exposing the pen point Ia for operating writing requirements. When it is desired to close the pen, the cap I is slid forwardly upwardly, carrying with it its dependent parts and lid I6, and just before completing its stroke the lid I6 is swung backwardly and caused to firmly, lockingly, and efiiciently close the cap, as illustrated in Fig. 1. This closing action of the lid is automatically performed by the engagement of the projections 24 of bar 20 with the transverse strip I2, just prior to the completion of the upward stroke of the cap I, which causes the bar 20 to pull the lid I6 and swing it to a locked closing position over the terminal of cap I. It will be noted that due to the automatic opening and .closing actions of the lid I5 there is precluded any contact thereof with the pen point Ia. l

If desired the pen barrel I may be provided with'a scabbard 30, to conceal the showing depression 9 when the fountain pen is in closed state, as illustrated in Fig. 11.

According to the modification shown in Fig.

to said cap within its terminal. a lid hinged to said collar to open and close the cap.-a bar hinged to said cap lying longitudinally between the cap and barrel and frictionally engaging the can and barrel, said frictional engagement of the bar causing it to open said lid upon initial rearward movement of said cap and to close said lid upon termination of the forward movement of the cap, and said collar being longitudinally slidable in said terminal to facilitate the open- 10 ing and closing action of said lid.
